Struct len_constraints::slice::Relative

pub struct Relative<'a, T, Op: Operator, By: TypeNum> { /* fields omitted */ }

An immutable slice with a relative length as length constraint

Note: Unlike the other constrained slices, this type does not validate the constraint on construction but on deconstruction (self.try_into())

Methods

impl<'a, T, Op: Operator, By: TypeNum> Relative<'a, T, Op, By>

pub fn get_slice(
    self,
    relative_to: usize
) -> Result<&'a [T], Box<dyn Error + 'static>>

Computes the expected relative length from relative_to, validates the wrapped slice against in and returns it on success
